The Worldvolatility will likely approach the 4% level soon, in what will be the 9th time since 1974. The road there can be longer or shorter mostly depending on Central bank policies going forward. The 90s saw the markets crawling close to 4% for almost two years. Whether the process will be quick or slow I will keep you posted.
